Camera lens front cover and the monitoring camera having the same

Abstract

A camera lens front cover and the monitoring camera having the same are disclosed. The monitoring camera may comprise a main body, a lens module and a camera lens front cover. The lens module may be disposed on the main body and comprise a lens holder and a camera lens, wherein the camera lens may protrude from the lens holder. The camera lens front cover may comprise a cylindrical casing and a glass cap, wherein the cylindrical casing may be hollow, and there are two openings at both sides of the cylindrical casing, and the lens module may be disposed inside the cylindrical casing. The glass cap may be disposed on one of the openings of the cylindrical casing and one side of the glass cap may be disposed with a protrusion part for accommodating the camera lens protruding from the lens holder.

What is claimed is: 
     
       1. A camera lens front cover, comprising:
 a cylindrical casing, for accommodating a lens module composed of a lens holder and a camera lens, wherein the cylindrical casing is hollow and there are two openings at both sides of the cylindrical casing, wherein the lens module is of a monitoring camera, and the monitoring camera is a gun-shaped camera; and 
 a glass cap, disposed on one of the openings of the cylindrical casing, wherein one side of the glass cap is disposed with a protrusion part for accommodating the camera lens protruding from the lens holder. 
 
     
     
       2. The camera lens front cover of  claim 1 , wherein the protrusion part is circular, elliptical or polygonal. 
     
     
       3. The camera lens front cover of  claim 1 , wherein the protrusion part is a spherical surface. 
     
     
       4. The camera lens front cover of  claim 3 , wherein the cylindrical casing is a hollow cylinder. 
     
     
       5. The camera lens front cover of  claim 4 , wherein the glass cap further comprises a protrusion edge disposed on the other side of the glass cap. 
     
     
       6. A monitoring camera, comprising:
 a main body; 
 a lens module, disposed on the main body, wherein the lens module comprises a lens holder and a camera lens, and the camera lens protrudes from the lens holder; and 
 a camera lens front cover, comprising a cylindrical casing and a glass cap, wherein the cylindrical casing is hollow and there are two openings at both sides of the cylindrical casing; and the lens module is disposed inside the cylindrical casing; the glass cap is disposed on one of the openings of the cylindrical casing, and one side of the glass cap is disposed with a protrusion part for accommodating the camera lens protruding from the lens holder, wherein the monitoring camera is a gun-shaped camera. 
 
     
     
       7. The monitoring camera of  claim 6 , wherein the protrusion part is circular, elliptical or polygonal. 
     
     
       8. The monitoring camera of  claim 6 , wherein the protrusion part is a spherical surface. 
     
     
       9. The monitoring camera of  claim 8 , wherein the cylindrical casing is a hollow cylinder. 
     
     
       10. The monitoring camera of  claim 9 , wherein the glass cap further comprising a protrusion edge disposed on the other side of the glass cap. 
     
     
       11. The camera lens front cover of  claim 1 , wherein the cylindrical casing is disposed on a main body of the monitoring camera. 
     
     
       12. The monitoring camera of  claim 6 , wherein the cylindrical casing of the camera lens front cover is disposed on the main body of the monitoring camera.
